Rigidly secured to the inner end 0F the vertical web of theextension part g is a brace-rod or tube 11` bent, as shown in Fig. 5, atthe end and extending lengthwise oi? the structure and secured at itsopposite end to the corresponding foldable extension-piece g. Thisbracerod 11 has riveted to the lower side thereof at the 'curved part11', as shown in Fig. 5, a foot-piece or bracket 12, which is adapted torest upon the horizontal piece 12, which is riveted to the under side ofthe part m when the structure is extended, as shown in Figs. 4 and 7.The piece 11 therefore acts as a post or supporting part for the outerend of the piece d when extended into horizontal position.

14 designates a connecting-piece between the parts g and m. This pieceis riveted to the part g at 15 and pivotally connected to the piece inat 16, about which it turns when the bed is opened and closed, as shownin dotted lines in Fig. 7.

17 desiglnates a tubular brace-rod extending lengt wise of the structurefor rigidly securing together the outer ends of the extension-pieces g.(See Fig. 3.) V

1S designates a stud on which the end of the angle-iron n rests when thestructure is in closed position, as shown in Fig. 6, in order to keepthe fabric of the main frame .in a horizontal position. 19 alsodesignates a stud on the horizontal web of the angle-iron m of thestationary or main Jframe and against which the end of the angle iron nrests when the structure is open, as shown in Fig. 7, and is for the.purpose of preventing the extension-pieces d and g from accidentallyfolding should weight or pressure be applied to the outer end of the artg. It will be seen that when the extensible frame is slid ofi from thestationary or main frame i, k, and m that A the extension-pieces d and gare supported in horizontal alinement by the pivot e, brace 11, and thelink 14, the parts 11 and 14 transmitting the weight to the angle-iron mof the main frame.

19" desi nates a brace-rod secured in the short legs for rigidly holdingthe same in spaced relation to each other. The longitudinal brace-rod 22is also for rigidly securing the legs b in s aced relation, and lthebracerod 2 3 is for tiie same purpose. The corner brace-.pieces 24, 25and 26 are employed, as shovn, forv rendering the structure firm and:mgl l'-l l In the operation of. the device when 1t 1s desired to openthe. sofa so as to transform it into a bed of the ordinary width all(that is necessary ifor the opepator to do is to place the footonthefoot-piece 4, giving it a pressure ip theldirectipn indicated by thearrow 20. (Shown in Fig. 2.) This movement draws the levers w and stogether, as shown 1n Fig. 4, while at the same tune the levers t and zare opened, as shown in this figure, and inopenlng the device theextension-pieces d and g are pulled outward by the extensible frame bymeans of the levers q and 5 from the nested position shown in Fig. 2 tothe open position in Fig. 4 and at the same time carrying with them theattached one-piece fabric c, thus giving a level and uniform surface tothe fabric. 24 designates a guiilingpiece for the angle-iron n., securedto` the main frame, as shown in Fig. 2. stood that in extending thecouch-bed the main frame is pushed far enough to the left by the leversg and 5, so that the end of the angle-iron n is passed over and back ofthe holding-stud 19. When it is desired to close the bedstead, theoperator places his foot on the foot-piece 3 and with a downward pres.-sure which is transmitted to the levers t, q, and 5 (the lever pullingon the levers q and 5, which in turn is transmitted to the extensibleframework,) slightly lifts the inner end of the same so that the piece nis lifted free of the lug or stud 1.9, when with a continued downwardpressure the extensible frame is drawn forward or toward the right, thehorizontal web of the channel-iron n engaging with the antifriction-rollp and passing over the same to a closing position, as shown in Figs. 2and 6.

he jointed members d and g' are nested alongside of and into the mainframe, as shown in Figs. 2 and 7, the post 14 rotating through asemicircle. The braces 1.1 and 1,7 are shorter than the distance betweenthe legs 7c k, and therefore pass inside when the structure is folded.The jointed extensionpieces d and g rotate about the rivet-points ,f,and 16, as shown in dotter lines 30 in Fig. 7. It will be understoodthat the extensible frame a, b, b', and n acts upon the pieces d and gthrough the levers q and 5 so as to pull them into alinement when thebed is opened and pushes on them when the bed is folded. When the bed isopen, the fabric yis of course placed under the requisite tension whenthe auxiliary frame is locked behind the lug 19.
